CAR-AXLE-BOX LID.

SPECIFICATION forming' part of Letters Patent No. 566,047, dated August18, 1896. Application filed October 22,1895. Serial No. 566,573. (Nomodel.)

To a/ZZ whom it may concern:

Be it known that we, HENRY C. W'ILLIAM- SON, residing at MichiganL City,La Porte county, State of Indiana, and CHARLES A. SCHROYER, residing atChicago, in the county of Cook and State of Illinois, citizens of theUnited States, have invented certain new and fuseful Improvements inCar-AxlesBox Lids; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to a novel construction in a car-axle-box lid,the object being to provide an improved and more efficient device ofthis construction.

The invention consists in the features of construction and combinationsof parts hereinafter fully described and specifically claimed.

In the accompanying drawings, illustrating our invention, Figure l is avertical section of the car-axle box and lid constructed in accordancewith our invention and with the lid closed. Fig. 2 is a similar viewwith the lid' open. Fig.- 3 is a cross-section taken on the line 3 3 ofFig. l. Fig. 4 is a vertical section of a car-axle-box lid constructedin accordance with our invention and showing the lid closed, and alsoillustrating the `manner in which the pocket 5 can be located in adifferof this kind, and to hold the spring to the lid,

as well as to permit its ready insertion, various constructions havebeen proposed possessing to a certain degree objectionablecharacteristics, which it is the object of this in vention to overcome.

In accordance with the principle involved by our invention we constructthe car-axle boxl in the usual mannerthat is to say, provided with theshoulder or vprojection 2, to

which the lid is pivoted. The lid 3 is construoted in the usual manner,except so far as my invention applies to it, and is pivoted to theshoulder or projection 2 of the car-axle box. The plate-spring 4 isemployed to hold the lid 3 firmly against the box l, or to hold it in anelevated position, as shown in Fig. 2, and to secure this spring 4 tothe lid and to permit its insertion we employ a pocket 5, which issituated on the inner face of the lid. This pocket 5 is preferably castintegral with the 4lid and is wider at its lower end, in a directionperpendicular to the plane of the lid, than at its upper end and istransversely of a width to receive the plate-spring. Said pocket 5 isprovided with a shoulder 6 on the lower end of the inner face of theinner wall thereof, against which the end of the spring abuts. Betweenthis shoulder 6 and the lid is a slot or opening-7, through which thespring can pass. Adjacent to the pocket 5 and on the inner face of thelid 3 are'two lugs or guides 8, between which the spring is situated,and which serve to hold thespring against lateral displacement.

It will be noted that the pocket or recess in the lid adapted to receivethe lug or projection 2 begins where the guides S are situated, thusforming a bend 9 in the lid at this point, which is adapted to act as afulcrum over which the spring is bent. As the tendency of the spring isto assume its original. straight form, the said fulcrum will direct itsresiliency so as to hold one end of the same in engagement with theinner face Vof the vinner wall of said pocket 5 and thus prevent saidend of said spring from passing over said shoulder 6.'

In use, after the lid 3 has been pivoted to the projection 2 it israised to the position shown in Fig. 2. Then the plate-spring 4 isinserted through the slot 7 of the pocket 5, as

shown in dotted lines in said Fig. 2, and is driven inwardly until itsinner end `strikes the upper face of the projection 2. Then by furtherdriving the spring the outer end thereof passes over the said upper faceof the projection 2, the middle portion at this time coming in contactwith said fulcrum 9, over which it is bent during its passage, to aposi- IOO tion shown in full lines in said Fig. 2., and when it reachesthis position the outer end of this spring will have just passed theedge of the shoulder 6 and by its resiliency will spring past theshoulder, so that it will be held irmly in position. When the spring isthus driven and the lid is in this position, the spring exerts a forceto hold the lid in the elevated position; but when the lid is throwndownwardly to close the box, as shown in Fig. l, the spring will thenexert a tendency to hold the lid closed against the open end of the box,as will be plainly obvious. It will be obvious that the spring may alsobe inserted in said pocket 5 before the iid is pivoted tothe projection2 and the spring compressed by placing its free end against saidprojection 2 and pressing the lid inwardly until the pivotopenin gstherein are iiush with the pivotopening in said projection 2.

It will be seen from the foregoing description that this lid can be castand that there are no openings through the lid, as is usual in lids nowcommonly used, and that while the spring serves to hold the lid in thedesired positions it does not project through the lid, and consequentlyno openings are made through which dust and dirt can enter the caraxlebox. It will be seen, further, that a special forni of spring isunnecessary, it being sufiicient to employ a straight plate-spring of alength to reach from the pocket 5 on the lid, as shown in Fig. l, oversaid projection 2 to a point adjacent the end wall of the pocket orrecess adapted to receive said projection 2. It will be further notedthat should the spring break or become useless it will never leave anopening in the lid through which dirt and dust can enter, and, further,the spring can be readily replaced without removing the lid from theboX.

We claim as our inventionl. A caraxle-box lid provided on its inner facewith an inwardly-extending pocket having openings between the inner wallthereof and the inner face of the lid, a shoulder on the lower end ofthe inner face of the inner wall of said pocket, and a spring having oneend situated within said pocket and adapted to abut against saidshoulder.

2. A car-axle-box lid provided with an in wardly-extending pocket uponits inner face and at its lower end, an opening atn the upper end ofsaid pocket, a shoulder on the lower end of the inner face of the innerwall of said pocket, an opening between said shoulder and the inner faceof said lid, and a spring having one end situated within said pocket andadapted to abut against said shoulder.

3. The combination with a car-axle box provided with a shoulder 2, of alid pivoted thereto, va pocket on the inner face of said lid, an openingin the upper end of said pocket, a shoulder on the lower end of theinner face of the inner wall of said pocket, an opening.

between said shoulder and the inner iace of said lid, a fulerum on saidlid, and. a platespring having one end. situated within said pocket andadapted to abut against said shoulder and bearing against said fulcruinand said projection 2.

4. A car-axlebox lid provided with an inwardly-extendin g pocket on itsinner face and adjacent to its lower end portion, an opening at theupper end of said pocket, a shoulder on the lower end of the inner faceof the inner wall of said pocket, an opening between said shoulder andthe inner face of said lid, a fulcrum on said lid, guide-lugs adjacentsaid fulcrum, and a spring having one end situated within said pocketand adapted to' abut against said shoulder, said spring passing oversaid fulcrum and between said guidelugs.

In testimony whereof we affix our signatures in presence of twowitnesses.
